Pit perforation

Innovative method of production casing perforation by punchers with the opening area of 6.4 cm2 per one puncture with simultaneous flushing of caverns by 8 hydraulic monitors.

Developed and implemented by NEKKO’s specialists in 2017.

The partners note the positive experience of using the technology and are satisfied with the results of the work.

Perforation parameters

• Hole area – 6.4 cm2

• Height of the opening area – 4 cm

• Opening area of the production casing – 18 holes/linear meter

Advantages of Pit perforation

  1. Allows perforating in wells with low static levels

  2. Ensures safety of work and absence of explosiveness during perforation

  3. Gentle opening of production casing, prevention of behind-the-casing circulation

  4. PIT perforation is 3 times faster than all known mechanical perforation methods

  5. Allows you to combine works within one well operation, depending to the technological tasks of the Customer
